BARREL-CATCH FOR REVOL'i/ERS.

To all whom "it may concern:

Be it known that I, HENRY IV. KoLB, a citizen of the United States,residing at Philadelphia, county of Philadelphia, State of Pennsylvania,have invented a new and useful Barrel-Catch for Revolvers, of which thefollowing is a specification.

My invention relates to a new and useful barrel catch for tire arms andconsists of a pin or bolt adapted to be seated in a suitable recess inthe frame of the fire arm in order to lock the barrel in position.

It further consists in providing an inclined face on the head of the pinor bolt for permitting automatic locking of the barrel.

It further consists of other novel features of construction, all as willbe hereinafter fully set forth.

Figure 1 represents a side elevation of a revolver embodying myinvention. Fig. 2 represents a top plan view of a portion thereofshowing the barrel and cylinder partly depressed. Fig. 3 represents aside elevation of a portion of the mechanism shown in Fig. 1, showing aportion of the barrel and cylinder in depressed position. Fig. 1represents a rear elevation of the parts seen in Fig. 2. Fig. 5represents a rear elevation of some of the parts shown in Fig. 1. Fig. 6represents a sectional view on line c0m Fig. 1. Fig. 7 represents asectional view showing the parts in difierent position from that seen inFig. 6.

Similar numerals of reference indicate corresponding parts in thefigures.

Referring to the drawings, I have found in practice that it is essentialfor the barrel to be firmly locked to the frame of the fire arm and toprovide means for the easy release of the same when properly manipulatedand also that the barrel may be locked again in position after havingbeen depressed by lifting or raising the same.

My invention is designed to accomplish these results and in the drawingI have shown one form thereof which is at present preferred by me,although it is to be understood that the arrangement of the parts may bevaried and other instrumentalities may be employed which will comewithin the scope of my invention and I do not therefore desire to belimited in every instance to the exact form as herein shown anddescribed but desire to make such changes as will be necessary.

Serial No. 591,294.

the present instance, shown as va revolver having the barrel 2 andcylinder 3, pivotally mounted in any suitable manner. Extending upwardlyfrom the frame 1 at suitable points therefrom are two lugs 41 and 5 suitably spaced apart one of which as, in the present instance, the lug 5,being provided with the recess 6 of curved contour, as best seen in Fig.3. It will be noted that the upper wall of the lug 5 is inclined orbeveled at 7 8 designates an extension on the barrel having a neck ornarrowed portion 9 in which the lugs 4 and 5 are adapted to be seatedwhen the barrel is in its normal firing position and locked there, saidneck portion forming shoulders 10, the walls of which are inclined, asbest seen in Fig. 3.

11 designates a pin or bolt which is movably mounted in the extension 8,which pin is provided with a head 12 and a thumb piece 13 against theinner wall of which, in the present instance, one end of spring 1 1bears, the opposite end of which bears against the wall of the recess 15in the eX- tension 8 this being best understood from Fig. 6.

It will be noted that the head 12 is adapted to be normally seated in asuitable recess or countersink 16 formed in one side of the extension 8and said head is so positioned that a portion thereof will projectbeyond the inclined wall of one of the shoulders 10, this being bestunderstood from Fig. 3.

It will be noted from Fig. 6 that the head 12 is formed with a taperededge, as at 17, and that when the barrel is in its normal firingposition a portion of the head 12 is seated in the recess 6 in the lug 5by which means it will be seen that the barrel and cylinder are firmlylocked in position. In order to release the same the operator pressesagainst the thumb piece 13 compressing spring 141 into the position seenin Fig. 7 and causing the head 12 of the pin 11 to be removed fromengagement with the walls of the recess 6 whereupon the barrel andcylinder can be swung upwardly on their pivot, as will be evident.

In order to return the barrel to its normal position it is onlynecessary to rotate the same in a suitable manner upon its pivotalpoint, which will cause the inclined face of the head 12 to ride uponthe inclined edge 7 of the lug 5 automatically causing the head 12 to beforced outwardly compressing-the spring 14, in order to permit passageof the extension 8 to its proper position, that is, until the head 12 isin line with the recess 6 and the countersink 1.6 immediately upon whichthe spring 14 will draw in the head 12 seating the same again in therecess 6 and so looking the barrel in position.

It will be noted that the walls of the countersink 16 are also inclinedor conical in order to properly coact with the inclined edge or conicalshape of the head 12, in order to provide for the proper seating of saidhead and a further advantage derived from this is that any wear whichmay occur will permit the head to be properly received and seated in thecountersink thus providing that the pin or bolt can serve as a positivelook at all times. It is for this purpose that I have made thecountersink or recess 16 of sufficient depth to permit of the furtherinward movement of the head 12 should parts wear.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. Ina device of the character stated, a frame, a barrel pivotallymounted thereon, an extension on said barrel having a lateral passageand a countersink, the wall of which converges inwardly, a pin movablyand rotatably mounted in said passage and having a head adapted to seatin said countersink, the wall of said head circumferentially convergingand adapted to engage the converging wall of said countersink to limitthe inward movement of said pin, said countersink being deeper than thethickness of said head to provide for wear, and a lug on said framehaving a recess therein the walls of which converge and which is adaptedto seat a portion of said head, when the barrel is in operativeposition, whereby the parts are locked together.

2. In a device of the character stated, a frame, a barrel pivotallymounted thereon, an extension on said barrel having a passage and acountersink, the wall of which converges inwardly, a pin movably androtatably mounted in said passage and having a head, a portion of whichis adapted to seat in said countersink, a lug on said frame having arecess therein adapted to seat a portion of said head when the barrel isin operative position, the wall of said recess converging and said headhaving a circumferential converging wall adapted to engage theconverging walls of said countersink and of said recess, saidcountersink and recess being deeper than the thickness of said head toprovide for wear and insuring the locking of the parts, and resilientmeans for holding said head in, and for returning the same into, saidcountersink and L'GCGSS.
